Treetop Kingdom is a large network of tree homes in the forest of Third Earth. It is the home of the Warrior Maidens including Willa and her sister Nayda. The Treetop Kingdom has often come under attack from the Mutants, usually because it is caught in the midst of the battle between the Mutants and the ThunderCats.
